How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

High-Pressure Socket-Connect
Steel Unthreaded Pipe Fittings
Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings have heavy duty construction that stands up to high-pressure applications. They are for use in noncorrosive environments.
Socket connect x butt weld straight adapters are also known as half couplings.

High-Pressure Socket-Connect Stainless
Steel Unthreaded Pipe Fittings
Forged for excellent strength, these heavy duty socket-connect fittings stand up to high-pressure applications. They are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

Thick-Wall Plastic Pipe Fittings for Water
Connect these fittings to Schedule 80 pipe–they have thicker, stronger walls than standard-wall fittings so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Fittings are plastic for good corrosion resistance. They meet ASTM D1784 specifications and testing requirements for material quality.
Fittings for drinking water meet NSF/ANSI Standard 61.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
To prevent leaks in threaded connections, apply a sealant to the male threads. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

CPVC Pipe Fittings for Hot Water
Made of CPVC, these fittings can handle high temperatures up to 200° F. They connect to Schedule 80 pipe and have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing and waste water treatment. Fittings have good corrosion resistance. They meet ASTM D1784 specifications and testing requirements for material quality. They are comparable to Corzan.
Fittings for drinking water meet NSF/ANSI Standard 61.
Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Fittings with Neoprene Rubber Gaskets: ASTM D1784, NSF/ANSI 61 - Pipe Nipples and Pipe: Use Schedule 80 CPVC Plastic
- Flanges: Use Class 150 CPVC Plastic
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a CPVC primer and cement (also known as solvent weld).
To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant to the male threads. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through a wall, tank, or panel to create an inlet or outlet for faucets, pipes, and spigots.
